In this paper we present three case studies of the installation of a stirling-cycle high temperature heat pump applied to recycling thermal energy including steam generation. Many industries have heat demand at temperatures above 100°C and often the preferred energy carrier is steam. The optimal integration of a heat pump can be determined by investigating the thermal need of the process with pinch technology. For many industries, the pinch temperature is too high for conventional heat pumps. We present a heat pump solution that can recycle thermal energy and deliver this to a heat source up t

Abstract:

In the paper, it is investigated that economics is the main advantage of thermal pumps. The financial costs during the heating season are almost three times lower than natural gas. You do not need any permissions to connect. The operation of heat pump units is absolutely safe and environmentally friendly. Since ancient times, heat pump units have been used as alternative heating systems. Such systems are reliable, have a long term of operation and are the most environmentally friendly. Heat pump units are seen as a new step toward the development of more efficient and safer systems. The main h

Water consumption is determined by unevenness and is formed under the influence of many, often uncontrollable factors. The inconsistency of the planned water supply regime with the actual water consumption leads to excessive pressures, which causes not only direct overconsumption of electricity at pumping stations, but also increases the likelihood of accidents in the network, contributes to greater water losses due to leaks in the water supply network. additional overconsumptio
